I flashed the TOP BIOS and was able to run with the 8.12s....unfortunately I haven't been able to get a decent OC on my card yet. I'm running my Sapphire 4870X2 on water with a full coverage XSPC Delrin block, and temps are great.
I'm going to attempt to edit the TOP BIOS to higher voltage....we'll see what that yields.
Will this BIOS actually allow 1.35V as shown in the RBE 1.18 BIOS table?
